Ricky was blown away by our 420bhp, 800Nm Stage 2 435d.
We had the privilege of showcasing our client AJ's stunning 435d on one of the UK's biggest car channels, with 400,000 subscribers and millions of monthly viewers.
This build was truly special, with us handling everything from performance upgrades to lowering, exhaust mods, and visual enhancements.

More Performance, Less Fuel

"To say I'm happy is an understatement''
Our client Ted recently did his homework on our business and made the decision to drive over two hours to have a Stage 2 performance package installed on his BMW 435d.
To make his visit more convenient, Ted stayed overnight at a local hotel, and we provided him with one of our complimentary courtesy vehicles while we transformed his car.
By midday the next day, Ted’s 435d was pushing an impressive 400bhp and 800Nm of torque, with a 0-60 time of just 3.7 seconds! But that’s not all—on his drive home, Ted reported an unexpected bonus: a fuel efficiency improvement of over 3mpg.
With over a decade of tuning experience, we've consistently found that tuning diesel engines—especially with our Stage 2 packages—not only boosts performance but also improves fuel economy thanks to the increased torque.
At Ecomax Tuning, we take immense pride in delivering top-tier service to every client, ensuring they leave with a smile and a high-performance vehicle to match!

Yes – all of our remaps are fully custom, whether you choose a road (flash) remap with a test drive or opt for a full dyno tuning session.
A flash remap will still deliver very similar power gains and provide excellent results, making it a great option for most vehicles.
With a dyno session, you get the added benefit of:
A before & after power printout
Live data feedback, allowing us to fine-tune the calibration precisely to your vehicle’s real-world performance
Manufacturers have to appeal to a wide range of drivers and uses, including lower insurance groups, tax brackets, emissions targets, and global markets. As a result, many vehicles are detuned from the factory.
It’s common for the same engine to be sold in multiple power outputs — for example, the Ford Transit 2.2 diesel available as 100bhp, 130bhp, and 170bhp — with the difference being software, not hardware.
Vehicles also need to run reliably in different climates and fuel qualities worldwide, so manufacturers leave large safety margins.
We simply unlock the safe, usable performance already built into the engine, never exceeding its limits. Reliability always comes first — which is why experience and a proven track record matter when choosing a tuning company.
All our remaps are safely within the tolerances of a healthy engine and turbo. We perform thorough health checks both before and after tuning. These engines can handle up to 550bhp and 1000Nm, so our packages remain well within safe limits.
Yes tuning your car is legal! However for your vehicle to be road legal your require all of your emissions systems to be in place including your DPF so if you choose the stage 2 or stage 3 packages this is for off road use only.
You should always declare any modifications, including tuning, to your insurance company. Failure to do so could invalidate your coverage if a claim is made.
However, Stage 1 and Stage 1+ remaps require no hardware changes and are 99% undetectable. Why not 100%? Only dealer-level diagnostics can detect them. From experience, inspections are usually done by companies without access to dealer-level software.
Remaps are undetectable by standard diagnostics used by most garages, and even we have to dig deep to check if a vehicle has been mapped. In our experience, no client has been caught out by not declaring tuning.
With over a decade of tuning experience, we've consistently found that tuning diesel engines—Stage 1 or Stage 2—not only boosts performance but also improves fuel economy thanks to the increased torque.
This is also backed up by our clients feedback and reviews!
For flash (road) remaps, allow around 1–2 hours. You’re welcome to wait with the vehicle, drop it off, or post the keys through our letterbox out of hours if that’s more convenient.
For dyno tuning sessions, the average time is 4–5 hours. Courtesy vehicles are available on request and are free of charge, subject to availability.
You can pay over 3, 4, or 6 months up to £1,000 with no credit check required.
For amounts over £1,000, you can spread the cost over up to 12 months, subject to a credit check.
All options are 100% interest-free.
More smiles per mile! Extra power not only makes overtaking safer but also transforms the car's overall performance, even when driving economically.
A remapped car is more responsive, with better power delivery, especially at low RPMs. This means smoother acceleration to speed limits without pushing the engine hard.
Lastly, you get the thrill of a more powerful car without needing to buy a new one. The added power guarantees satisfaction!
Tuning alone doesn’t change your car’s sound, If you’re after more sound, we can discuss options to help you unlock the potential your car has with a custom exhaust.
